HOT WATER l-l EATER.

SPECIFICATION forming part of Letters Patent No. 378,633, dated February 28, 1888.

Application filed January 15, 1857. Serial No. 224,427. (No model.)

To ttZZ whom it may concern:

Be it known that I, JAMES M. Tnavnn, of Randolph, county of Norfolk, and State of Massachusetts, have invented an Improvement in Hot-Water Heaters, of which the following description, in connection with the accompanying drawings, is a specification, like letters and figures on the drawings representing like parts.

This invention has for its object to construct a hotwater heating apparatus whereby the heat-distributing medium-i. 6., water contained in ajacket surrounding the furnace or fire-pot-is enabled to circulate freely from the top of the heater through pipes back to the base or bottom of the water-jacket.

The invention consists of the apparatus op erating after this manner for heating by hot water, constructed and arranged essentially as I will now proceed to specify and, in conclusion, particularly claim.

Figure 1 shows in vertical section a heater and a sufficient number of pipes to illustrate the present invention; and Fig. 2, a top or plan view of Fig. l with the pipes removed, the said figure showing the distributer as provided with a number of openings.

The interior wall, a of the heater is surrounded by a conical top part, a, thus forming a combustion'chamber, in which is placed a grate, a, and surrounding all is a waterjacket, a a, leaving a water-space, a. The interior of the heater is reduced in diameter until the top of the combustion-chamber terminates in a conical point or sharp edge, 2, while the outer shell or casing, a c of the water-jaeketis kept substantially parallel with the interior a a of the combustion-chamber to form about the point or edge 2 an outlet or passage for the discharge of water from the water-jacket.

Suitable smoke lines, as e are formed through the interior a and the water-jacket to lead smoke out from the combustion-chamber.

The apex or point 2 of the shell of the combustion-chamber lies at the center of the outlet-orifice of the water-j acket. A distributor, c, of frusto-conieal shape, is attached to the outlet of the water-jacket, the smaller open end of the said distributer being of the same diameter as the diameter of the said outletorifice, so that when the distributer is placed upon and bolted to the outer wall of the water-jacket, as by the bolts b, a continuous, free, and unobstructed passage is presented to the distributer.

The distributer is provided centrally with a conical separator, c, of sufficient size to leave a space between the cone 0 and the outer wall of the distributer of substantially the same width as the width of the outlet from the water-jacket, the apex of the conical separator c occupying a position directly in line with and quite near to the apex 2 of the portion a of the heater.

The upper end of the distributer or dis tributing-chamber, as it may be termed, around the base of the conical separator c, is provided witha series of holes or openings, 0, (see Fig. 2,) into which the circulationpipes are fitted or otherwise attached, the number of holes depending upon the number of circulatioi'i-pipes employed.

I have herein shown in section one circulat' ing-pipe, it being fitted into the distributer c at the top and returning to the lower end of the water-jacket a to complete the circuit.

The single pipe a, fitted into the top of the distributer c, is provided with a coupling, M, of peculiar construction, the coupling receiving two branch circulating-pipes, n n, which convey the water to different parts of the building, said pipes being shown as joined by a peculiar coupling, m, to a single pipe, as a, connected to the water-jacket.

The couplings n and m are provided at their interior with a projecting division-wall or separator having a sharp edge produced by the meeting of two curved surfaces, as 6 7, such point of junction or meeting of the two curved surfaces coming directly opposite the center of the inlet-port of the coupling, so that the entering water strikes the said sharp edge, and is thereby divided, each half or portion freely moving into the respective pipes M11 This form of coupling avoids the friction usually caused by water striking a flat interior surface, as of an ordinary coupling.

The two branch pipes are joined to the pipe a by the coupling m, the interior of' which is provided with curved surfaces similar to that of coupling a, above described, so that should the water flow faster in one pipe, as n, than in the other, as n, the affinity of the particles e I emcee of the one stream for the particles of the other would, under such circumstances, by commingling one with the other, increase the movement of one and retard the other to equalize the 5 force of the stream as soon as possible, so as to prevent the friction ordinarily produced when two streams meet in an ordinary T-coupling.

It is obvious that, instead ofjoining both of the branch pipes it??? to the return-pipe a 10 one of the said pipesasn for instancemay return directly to the lower end of the waterjacket, and the other to be coupled with the return-pipe 92 The pipefmay serve to illustrate this construction last referred to as ap- 15 plied to pipe a I claim-- In an apparatus for heating by the circula' tion of hot water, the heater consisting of the water jacketed combustion chamber having the conical top part provided with the dividing-wall 2, in combination with a combined Separator and distributer, 0, arranged sulo- JAMES M.
